Hook size depends on what size carp you want to watch. Snag fishing with smaller hooks is not a good idea. A smaller hook is not durable enough to hold a big carp. So, it would help if you had a big size hook for a giant catch. As like, a number-2 size hook is perfect for catching 32 lbs carp. When it comes to baits on a hook, a 10 mm bait will accurately fit on an 8 number hook. You can use hook coloring techniques to catch them easily. As like, you can use a brown hook on muddy areas.
